HINT:  Getting slow download speeds from ftp.slackware.com?
Give slackware.osuosl.org a try.  This is another primary FTP site
for Slackware that can be considerably faster than downloading
directly from ftp.slackware.com.

Thanks to the friendly folks at the OSU Open Source Lab
(http://osuosl.org) for donating additional FTP and rsync hosting
to the Slackware project!  :-)

Also see the "Get Slack" section on http://slackware.com for
additional mirror sites near you.
